WINDDW SCREEN.

Specification of Letters Patent.

Patented May 30, 1922.

Application led September 9, 1920. Serial No. 409,091.

To ZZ whom t may concern:

Be it known that I, CHARLES S. MYERS, citizen of the United States, residing at Hazleton, in the county of Luzerne and State of Pennsylvania, have invented certain new and useful Improvements in l/Vindow Screens, of which the following is a specification.

This invention relates to improvements in ventilators and more particularly to window screens.

An important object of this invention is to provide a window screen having novel means whereby the wire fabric may be readily and economically renewed without the exercise of any unusual. skill.

A further object of the invention is to provide a metallic screen having a wooden core to which the wire fabric is attached and which by reason of being enclosed within the metallic strips from which the screen is made, is prevented from rotting or decaying.

The invention further aims to provide a metallic screen which is neat in appearance, desirable in use, and cheap to manufacture.

Other objects and advantages of the invention will be apparent during the course of the following` description.

In the accompanying drawings forming a part of this application and in which like numerals are employed tol designate like parts throughout the same,

Figure 1 is a perspective ofthe improved screen applied,

Figure 2 is a horizontal section on the line 2-2 of Figure 1,

Figure 3 is a horizontal section taken on the line 3&3 of Figure 1,

Figure 4lis a vertical sectional view taken on the line 4-4@ of Figure 1,

Figure 5 is a sectional view taken on the line 5-5 of Figure 1,

Figure 6 is a perspective of one section of the screen detached,

Figure 7 is a fragmentary perspective of another section of the screen.

In the drawings, wherein for the purpose of illustration is shown a preferred embodiment of the invention, the numeral 1() designates a window frame or casing within which the improved screen may be arranged.

A screen constructed according to this invention embodies eoacting slidably connected sections generally designated by the numerals 11 and 12, and by reason of the fact that the sections of the screen are slidably connected the screen may be readily and conveniently adjusted when arranged within the window frame.

rFhe section 12 of the improved screen comprises a channeled frame 18 which, as illustrated in Figure 6, is of rectangular formation and 'L2-shaped in cross section. The frame 13 which is of metal is open in one side and receives a core 14 of wood. The core 14V is also rectangular in formation and forms the attaching means for a sheet of wire fibre 15 secured to the core by tacks 16 or other suitable fastening devices. lllith particular reference to Figure 6, it will be observed that the edge portions of the wire fabric are allowed to remain preferably flat upon the application of the screen to the frame and will not be crimped or seated within grooves, which is the case with many window screens now in use. By reason of the fact that the metal frame 13 will not yield to any great extent the wire fabric may be stretched tightly upon being secured to the core and further by reason of the rigidity of the frame the core will not be allowed to warp or bend inwardly. The core receiving frame 13 is adapted to be detachably arranged within an outer rectangular frame 18 so as to confine the core within the inner frame 13 and to effectively conceal the tacks and the edge portions of the screening 15. The outer frame 18 which, as illustrated in Figure L1, is L-sliaped in cross section, snugly receives the inner frame 13 so that when assembled the section 12 will be neat in appearance and will not be possessed of any objectionable projections. The outer frame 18, the inner frame 13, and the core 14 are formed with indent-ations 19 which serve to securely connect the parts of the section 12.

The section 11 of the improved window screen comprises an inner channeled frame 2O which., as illustrated in Figure 3, is U- shaped in cross section and is open in one side for receiving` the core 21 preferably of wood. Since the frame 20 is of rectangular formation, the core 21 is also of rectangular formation and forms an attaching means for a sheet of wire fabric 22 which is connected to the core through the medium of tacks or other suitable fastening devices. The core receiving frame 2O is similar in construction to the core receiving frame 13 and is adapted to be detachably received within an outer frame 26 which, as illustrated in Figure 3, is L-shaped in cross section and comprises an inwardly extending flange 28 adapted for concealing the edge portions of the screen and theI tacks 211 and a second iange 29 which extends about the sides of the inner frame.

lith particularreference to Figure 3, it will be apparent that the inner frame 2O of the section 11 is flatly engaged with the inwardly extending ange 28 so that the section 12 may be positioned at one side of the section 11 and adjusted with relation to Vthe same. A pair of the outer flanges 29 of the frame 26 are extended to form a pair of spaced parallel oppositely disposed members 3() having their longitudinal edge portions 32 extended inwardly and engaging the adjacent sides of the sections 12 so as to snugly but slidably connect the sections of the screen. It will, therefore, be noted that the flanges 29 serve not only as a means for securing the core receiving frame 20 in position but as a means for slidably connecting the sections off the screen. hen the section 12 is arranged between the guide members 30 the core receiving frame 2O is securely held in position. This applies also to the core receiving frame 13 which is held within the frame 18 by the inwardly extending edge portions 32 of the guide members 30.

As illustrated in Figure 2, the several frames of the screen are formed from flat sheet metal so that the wire fabric 15 is positionedclose to the adjacent side of the section 11 for providing a means whereby flies and the like are prevented from passing between the sections of the screen.

As illustrated in Figure 6, one side of the frame 13 of the section 12 is extended laterally to form a guide flange 40 `which is adapted to be slidably received within one of the guide members 30. i This construction makes the upper edge of the screen comparatively smooth so that when engaged by the lower portion of a sash 11, fiies will be effectively excluded. With reference to Figure a, it will be observed that the flange a() formed at the upper edge of the section 12 has its end portion extended inwardly into engagement with the retaining frame 18 so as to c0- operate with the indentations or notches 19 in holding the outer frame 18 firmly in position.

The inner frame 13 ofthe section 12 is provided at `a point adjacent one end with a transversely extending rod 42 having its end portions extended angularly flatly along the sides of the core 14C as indicated at 44, and

'then inwardly and laterally to form stop elements 46 adapted to provide a means whereby the extension of the screen will be liniited. iTVhen the screen is extended the laterally projecting stop elements 46 will engage the inner end of the frame 11 and when the entire screen is contracted, the spaced stop elements L16 will engage the outer end of the frame 11. Tn addition to forming the stop elements, the rod 42 serves as a positive means for strengthening and reinforcing the frame 13 and also prevents the adjacent portion of theV wire fabric 15 from bulging. Thus, by preventing the wire fabric from bulging, flies and the like are prevented from passing through the window between the sections of the screen. 80 In assembling the improved screen, the cores 14 and 21 are arranged within the core receiving frames 13 and 20 respectively and the wire' fabrics 15 and 22 are subsequently tacked to the cores in the manner set forth. The core receiving frames and 20 may now be arranged within the frames 18 and 26 so as to secure the cores 14- and 21 in position and to effectively conceal the edge portions of the wire fabrics and the fastening means for the same. y

When desired, the wire fabric in either of the sections of the screen may be readily renewed by detaching the same from the cores. The sections of the screen may be lacquered or otherwise finished so as to give the screen a neat appearance.

, Tn arranging my improved screen in a window, the sections of the same are extended so as to be received within the U- shaped clips 50 secured tothe beading 51 of the window. As one section of the screen is offset with relation to the other section, the clips at one side of the window will be offset with relation to the clips on the otherV side.

Tn carrying vout the invention, a suitable light cloth may be employed in lieu of the wire fabric vso that the apparatus will be permitted to function as a ventilator `adapted for arrangement in a window or the like.

With reference to the foregoing description it will be apparent that a screen constructed in acordance with this invention may be readily and conveniently adjusted to windows of various sizes and when'in posi- 115 tion will effectually keep out fiies, mosquitoes and the like. Y l

It is to understood that the form of the invention herewith shown and described is to be taken as a preferred embodiment of the 120 same and that such minor changes in construction and arrangement of parts may be made as will remainwithin the spirit of the invention and the 4scopeof what is claimed.

Having thus described the invention, what 1.25 is claimed as new is:

1; A ventilator comprising a pair of slidably connected `sections one of which is provided with a frame, a foraminous body secured to said frame, and a rod traversing 130 said foramnons body and having its end portions secured to said frame and extended laterally to form stop elements.

2. A device of the class described including zi pair of slidably connected sections, foraminous bodies secured to said slidably connected sections, and a reinforcing rod extending across one of said sections and having its end portions secured along the sides of the same and extended inwardly and laterally to form stop elements adapted for limiting the movement of the sections with relation to each other.

i In' testimony whereof I alix my signature.
